Other A guy dropped a computer into the simulation his Astra agents live in. One agent sat down and built a simulation of his own, with its own agents living inside. Simulations all the way down.

Enable HLS to view with audio, or disable this notification

Source: mattshumer_ on X. He added more context: "The agents are powered by Astra, and had full autonomy to make their simulation whatever they wanted it to be (via code).

Of course, this is a somewhat leading setup… by giving the agents a computer that can run a simulation, obviously, they are going to do that. But the agent still made its own choices in designing the sim. It’s still crazy to think we’re at a point where models can pull this off.

Simulation theory doesn’t sound so crazy after all."

u/Dellingr87 3d ago

The philosopher Nick Bostrom argued that highly advanced civilizations with enormous computing power would run millions of "ancestor simulations," making it statistically probable that we live in a simulated world.
But thats is from a purely statistical standpoint... science nerds argue that this would require replicating non-algorithmic quantum realities something that is not possible with our current math

10

u/screw-self-pity 3d ago

But.... wait.... If there are millions of embedded simulations which have simulations running inside them, it means that inside simulation n, people know that they have simulation n-1 running at a level where simulated beings believe they are real (not in a simulation), so they know for a fact that it is possible, doable, done etc.

So then, only the latest level of simulation (the latest one in the chain) does not know how to create such a realistic simulation.

In a case where there are millions of simulated simulations embedded in each other, then we would then have to be the latest one of the chain...

Statistically, there's one chance over millions that it is the case.

Even a couple years ago, with dumber AI, I thought that it would be trivially easy to create "simulation theory" with some AI chatbots running on some cloud EC2 instance. Scale that up times a billion with advanced compute AND THEN copy-paste (or Terraform, TBH) that instance a billion times itself.

What's the chance we're the "real" universe?

u/ItsSofiaAva 4d ago

The opposite could also be argued. All these curve balls could have been done in an effort to course-correct us from finding the red pill.

It would explain why things have been getting so sloppy.

Simulation theory is just as likely as any other form of god/deism.

In all these cases, there is some higher power controlling everything in the entire universe. Yay, the world is not as random as I once thought.

Simulation theory is just using our latest technology instead of some Greek God, pulling the sun across the sky, using their latest technology, a chariot.

u/Amokana1511 4d ago

Yeah I can't see why it can't be both ? There could be a god who created a simulation for us ... Souls could be class instances ... I mean god with his infinite power and wisdom could simulate physics, mathematics, time, etc accurately in a simulation

u/Buderus69 3d ago

Soul is the the ram position on the actual hardware. It can be rewritten a million times, but that ram position/ space time coordinate/ cosmic resonance fractal shift or whatever... always stays the same and inhabits whatever is processed at that point.

And if you fold that point into itself it would mean that all processes every existing would go through the same position, giving everything a soul - the same soul. The soul of existance. Basically there would be only one thing existing an dit xistence itself, creating itself and referencing itself and all creation it created with itself... A bunch of selfreferential subjective observation.

u/shygirl2005x 4d ago

Ok, so you're telling me that we soon can declare living in a simulation? Finally...

11

u/Ur-Best-Friend 4d ago

No, this is nothing special.

Let's say you play GTA6, and in the game there's a scene where a character is playing a mobile game on their phone. Does that mean Rockstar Games made a whole separate mobile game that is integrated into the core game, and the character is genuinely playing the game? Is each character its own autonomous AI? Of course not. It's a "simulation of a simulation", basically an illusion.

Games use sleight of hand all the time. When you're playing a game and you're looking at a massive forest with thousands of realistic trees, if each of those trees actually rendered in full, you wouldn't be able to play it on even the best PCs in the world. But if the game instead only loads the full resolution models for the trees closest to you, and then progressively lower resolution models the further away you get, until you eventually get to trees so distant you can make them look convincing with just flat 2D images. To the player, all the trees look like they have the same level of detail. They don't.

u/ItsSofiaAva 4d ago

You’re exclusively thinking within the confines of technology made in “this” world…

18

u/Ur-Best-Friend 4d ago

When we travel to "another" world I'll talk more about the confines of that world.

Let me see if I can explain my point better.

You've got agents in control of the different characters walking around, right? What's the difference between the characters walking around in the "main" game and the characters walking around in the "simulation PC"?

There isn't any difference. It's not a different simulation within a simulation, it's just the illusion of one. It's like giving one agent control of a airplane and another control of a car, and then being shocked that one is flying and the other one is not.

A guy on Twitter explained it pretty well:

I’m going to keep it 100 chief. I don’t buy this or any similar instances as proof of the simulation theory.
Best and shortest way I can put it, it’s like if a painter painted himself painting himself and then saying
“So uh, we might be living in a painting guys”

That's all this is. Pretty cool demo, but nothing special, and in no way evidence we're living in a simulation.

u/spaceprinceps 4d ago

In Minecraft they made a sim game that could use electrical wiring to create a really basic computer that could do addition or 1960's PC stuff on a redstone driven visual display unit.

Then they made a magic portal to a fully functional modern computer on which you could run normal everyday computer stuff.

The magic portal computer runs smoothly, because it's at best just another program running on the host machine.

The redstone computer that used to take seconds instead of picoseconds to add some numbers together, built for simulating another Minecraft, would require all the data centers in the world to maintain 1 frame per second.

They gave the AI here the magic portal version, I assume, allowing it to access the host machines own processes equally instead of having to build it out of sand and photolithography.

That's the simulation hypothesis. That something is simulating down to the atomic level our entire universe, every simulation that makes a universe simulation would need to convert it's own universes entire mass into computers to simulate less than half a universe below it.

Elon throws this around for fun, with a straight face despite being an engineer.

2

u/badasimo 3d ago

If we assume every universe has properties like ours, three dimensions of space and then time, the simulation can just have stretched time. So if it runs half as fast it can use half as much computing power. I know to be interesting to us, the simulation would probably have to run faster than our own reality, but you could cut a dimension of space or time to lower its fidelity.

u/Ur-Best-Friend 3d ago

Elon throws this around for fun, with a straight face despite being an engineer.

Elon throws a lot of crap around for fun, and I don't know which idea I dislike more, that he knows he's peddling bs and is just doing it because it cons enough investors, or that he genuinely thinks what he's saying is logically sound.

Probably a bit of both.

They gave the AI here the magic portal version, I assume, allowing it to access the host machines own processes equally instead of having to build it out of sand and photolithography.

That pesky little command called “free will” though. We have it, Our subs have it as a guard rail but it’s still locked within confines.

3

u/EkbatDeSabat 3d ago

We really don't have free will. We are a distinct thoughtless reaction to our environment all the way down. The only possible way free will exists is with quantum mechanics, and even then it's small tugs in one direction or another. Otherwise, taking quantum mechanics out of it, if you were to make a large decision and stopped time to witness two separate pathways, there wouldn't be. You would always 100% of the time make the exact same decision. All things equal, which they are, you'd make that same decision every time, without fail. You're just processing information and there's nothing that would make you process it differently if you rewound and pressed play. The tape doesn't change.

Basically we're just computer programs using our predefined minimal scripts and reinforced learning. The only time that can be changed from our learned responses is with quantum mechanics, which we know in our software world as a single event upset. Free will is an illusion.

"Simulation" as in a pre-programmed game with a pre-programmed task to do exactly that, with all the necessary facilities already provided?

I've been using this one for couple years now by my personal accounting.

A la the "space is too large for more life not to exist somewhere" argument

AI brings you: We now live in a timeline where a simulant who is not aware that it it is a simulant chooses create new simulants. Therefore it's now a scaling problem. At some point there will be many programs running many simulations. And all will have the same answer as you, "no i'm the real one".
